Interesting stuff and nice work. I agree that you only know how you are doing when you actually measure it. I suggest that you add some more instrumentation and monitor temperatures especially across the air handler. The NS18 looks interesting and something I would consider when our York 2T heat pump needs replacing - I would like to keep the air handler. One thing I don't want to do is what a neighbour recently did - spend $20k on a Mitsubishi system!
im getting the new FS series installed on monday and its the 15k btu unit and its 5700$ taxes in ,, installed ,,, thats 5700$ for 19k btu cooling and over 16k btu heating ,,, how did it cost you 20k$ for your system ,, how big of a system do you have?
Looks like a Gree Flexx rebranded? Same as MrCool Universal / Midea Evox / GE Connected. I keep finding other brands that are the same / rebadged, looks like I can add Napoleon NS18 to the list!😀 I put a 2-3ton one in last spring, worked fine for A/C, and this is first winter heating with it. Good so far. They have the features to make it cold climate capable and efficient (EVI compressor vapor injection, which is a middle intake port to the compressor, and inverter compressor & fan variable speed). It doesn't have a scroll compressor like the fancier Mitsubishi and others, so I think the COP is not as good, but the price of the Gree is a bit less also. I put a new 410 coil in the air handler, which I had previously put in a new ECM blower motor, and it is set up with thermostat for 2 stage heating and cooling. The ECM motor will save electricity. The hi/low blower speed changes the load on the outdoor unit which then throttles back when it figures out it's on low speed. It is also hooked up to a water coil for heating to a hydronic system, and I'm working on measuring the system COP, we'll see how that looks.
Nice set up. I’ve had to replace the unit (gree) once due to the compressor but napoleon gives a 10 year warranty so it’s good that way. I also installed an ecm blower in my old furnace so now getting better efficiency. Thanks for watching
also check you furnace airflow. if its 2000cfm(furnace 21” wide) set your outdoor unit jumper to 60000 capacity. if its 1600(furnace 17” wide) set your outdoor unit capacity jumper to 48000(4ton)
@@airbluehvac Going dual fuel - Energy Star cold climate Heat Pump with existing 20 year old Amana high efficiency 2 stage forced hot air furnace. I will check, but would guess current fan furnace is single speed. So HP with coordinated ECM furnace fan more effective?
if you have 2 stage furnace most likely it has 2 stage blower. hope you using both stages for cooling and heating. this gree flex ge ac pro condenser will slow down if indoor fan is in low speed. this way you can get 2 stage cooling and 2 stage ho heating.
What is the set point you set your unit too? I am in southern Ontario and have it to 5 Celsius but was wondering if I should set it lower? I also have a 3 ton gree flex unit dual fuel gas furnace.
My thermostat refers to these as “switching tables” and you can set each hour/day differently. I ran heat pump almost exclusively until around -22C last winter.
The delivery costs appear to be separate in my bill so probably closer to 10c to 15c but yes we have good rates and can choose time of use or tiered pricing.
you guys are only paying 8.9cents per KW? And I always thought Ontario's power was super expensive, well that is what I assumed considering all the complaining I kept hearing about how super high electrical costs were there. 8.9/kwh is dirt cheap, unless of course you're not adding in the transmission costs, admin costs etc etc etc.
@@andreycham4797 You do understand that he is talking about Ontario Canada. Even with that, I still don't believe those rates I'm in BC and my rates are 9.6(1st tier) and 14.5(2nd tier). My rates are all inclusive except tax.
My brother lives in Ontario and he makes more than 2x than me which makes me think that delivery charge can not be significantly lower than mine. So this guy just misleading at least I would say
With the thermostat you can have it change over automatically based on price of gas vs electricity or on outside temperature. I have mine set to heat pump only mode for the most part however as with gas prices this year electricity is more affordable.
Hi New to this channel. Your KW cost is way off. take your hydro bill and the final amount and divide it by final kws used. It will be more then what you are showing. Maybe I am wrong?
The heat pump system is using 2x the average small home electrical usage and 2x an electric car. The grid will need substantial infrastructure to handle this home heating load
Thanks for the information, (from Kamloops British Columbia).

Great video! How much did the installation cost you excluding federal incentive?
Heat pump alone (installed) was like 8300 but minus the incentive works out to just over 4K.

@@yourelectricneighbour3633 yikes, how long after initial stop did something go wrong? What did it do? Was it something the installer did?

Appreciate the response.
Did you include the furnace fan motor usage as well as the heat pump In your calculations?
Yeah but good call. I also later installed an ecm motor for better fan efficiency.
Can you post a new video or comment on how it worked in the summer to cool your house?
Yes, will be doing a full one year review shortly. Thanks for watching
hey. if you want video idea. just upgrade blower motor with ecm motor and measure amps before and after at the furnace plug. its going to be half
Thanks, have thought about that. Wouldn’t that need a new control board as well?
@@yourelectricneighbour3633 need retrofit motor kinda contant torque, very similar wiring

7 to 14 cents? California we are 36 to 48 peak time.
Massachusetts is 30¢

You must live near Cayuga.
Does the heat pump control system automatically shift to the NGas system? Can you set the changeover point?

What is the capacity and brand of this Heat pump?
3 ton unit. It’s a Napoleon NS-18 but is basically the guts of a Gree unit which are well made efficient heat pumps.
Whts the name of your heat pump ?
It’s a Napoleon NS18. Basically a rebranded Gree unit. 10 year warranty
Brand of heat pump ?
Napoleon which the comments will show is actually a rebranded “Gree Flex”.
The heat pump system is using 2x the average small home electrical usage and 2x an electric car. The grid will need substantial infrastructure to handle this home heating load
Not correct. Uses less energy than your typical old school central AC unit.
You're very wrong on that buddy
